| + | [[Megan]] and [[Ponytail]] are in orbit while nanobots are devouring the earth in a swarm. The nanobots stop after devouring 40% of the planet. This is a take on the "[https://en.wikipedia.org/wiki/Grey_goo Grey goo]" scenario in which self-replicating nanobots destroy the earth while creating more and more of themselves non-stop. | ||
| − | + | However, the nanobots are only able to destroy 40% of the planet because 40% of the earth volume = (# of {{w|IPv6}} addresses) x (A few cubic microns). Without more IP addresses, the nanobots cannot continue to replicate (assuming that each nanobot must be individually addressable). | |
| − | + | IPv6 supports approximately 3.4×10<sup>38</sup> addresses while the {{w|Earth|Earth's volume}} is around 1.08321×10<sup>12</sup> km<sup>3</sup> or 1.08321×10<sup>39</sup> µm<sup>3</sup>(cubic micrometre). [[Randall]]'s guess on 40% of the planet would mean each nanobot is about 1.27331 µm<sup>3</sup> - which is still less than "a few cubic microns" according to [[1070: Words for Small Sets]]. Note however, that the nanobot density might be different than Earth density, so "a few microns" might still be correct. | |

This is a joke on the shortage of IPv4 addresses. The only difference is that we are on {{w|IPv4}} and the nanobots are on {{w|IPv6}}. | This is a joke on the shortage of IPv4 addresses. The only difference is that we are on {{w|IPv4}} and the nanobots are on {{w|IPv6}}. | ||
